IMPROVEMENT IN COMBINED HAiF-IS AND LOUNGES FOR INVALIDS.

Specification forming part of Letters Patent No. 136,962, dated March18, 1873.

To all whom it may concern.-

Be it known that I, DAVID Gr. BOARDMAN, of Albia, in the county ofMonroe and in the State of Iowa, have invented certain new and usefulImprovements in Combined Chair, Lounge, and Bed forInva-lids; andIdohereby declare th at the following is afull, clear, and exactdescription thereof, reference being had to the accompanying drawing andto the letters of reference marked thereon making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a combined chair, lounge, and bed for invalids, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a perspective view of my invention, showing the same as achair. Fig. 2 is a longitudinal vertical section of the same, showing itas a bed; and Fig. 3 is a view of a part of the side, showing a slidefor holding up a box under the seat.

A represents that part which forms the seat of the chair, supported bylegs B B suitably braced. which is hinged, as shown, to one end of theseat, and connected, by pivoted arms a, to a horizontal frame, D, whichslides in guides I) attached to the legs B B a suitable distance belowthe seat A. At the outer end of the frame D are legs B to support theframe in a horizontal position. The under sides of the side'pieces ofthe frame D are cogged, as shown, and the frame moved out and in atpleasure by means of two cog-wheels, d, on a shaft, 6, and this shaftturned by a crank at one end. At the other or foot end of the chair is asimilar horizontal sliding frame, E, with legs, and the side bars ofwhich are cogged on their under sides, and operated in precisely thesame manner by means of cogwheels d on a shaft, 6.

When the invalid desires arecumbent position or bed the back C may belowered to any ,position by extending the rear frame D, thus 0represents the back of the chair,

forming the head of the lounge or bed as desired.

On one end of the shaft 6 is a cog wheel, f, into which works a pawl, h,to hold the back 0 in any position desired. By extending the frontframeE the bed or lounge is completed G represents the foot board orstool, hinged between the front legs of the chair, and adjusted at anyheight or angle desired by straps m m.

The person occupying the chair can be placed in any desirable positionso gradually that they will hardly feel the changes. Invalids who haveany strength at all can do it all themselves, thus saving so muchtrouble and labor of waiting upon them.

In the center of the seat is an aperture, 02,

witha lid, H; and under said aperture is a box, I, hinged at one end,and supported at the other end by a slide, 12. In the box I is anotherbox, J, to contain a chamber-vessel, which interior box andchamber-vessel can be drawn out, when the box I is lowered, by withdrawing the slide 19. By this arrangement the patient can very easilyattend to himself without assistance.

The legs Band B are all to be provided with casters, so that the bed canreadily be moved to any place where desired.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The toothed frame D, pinion d, connecting-bars a a, and back 0,constructed and arranged as and for the purpose set forth.

2. The toothed frame E and its pinions or wheels (1, in combination withthe seatA and movable or adjustable back, as and for the purpose setforth.

3. The box I hinged to the chair-frame beneath the seat, said box beingsupported or held in position and used as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of D. G. BOARDMAN.

. December, 1872.
